58	* Handle to the PDEV returned by the drivers DrvEnablePDEV routine.
59	* pHalInfo
60	* Points to a DD_HALINFO structure in which the driver should return the hardware capabilities that it supports.
61	* pdwNumHeaps
62	* Points to the location in which the driver should return the number of VIDEOMEMORY structures pointed to by pvmList.
63	* pvmList
64	* Points to an array of VIDEOMEMORY structures in which the driver should return information about each display memory chunk that it controls. The driver should ignore this parameter when it is NULL.
65	* pdwNumFourCCCodes
66	* Points to the location in which the driver should return the number of DWORDs pointed to by pdwFourCC.
67	* pdwFourCC

1964	//
1965	// Takes a pointer to a partially or fully filled in pThisDisplay and a pointer
1966	// to an empty DDHALINFO and fills in the DDHALINFO. This eases porting to NT
1967	// and means that caps changes are done in only one place. The pThisDisplay
1968	// may not be fully constructed here, so you should only:
1969	// a) Query the registry
1970	// b) DISPDBG
1971	// If you need to add anything to pThisDisplay for NT, you should fill it in
1972	// during the DrvGetDirectDraw call.
1973	//
1974	// The problem here is when the code is run on NT. If there was any other way...
1975	//
1976	// The following caps have been found to cause NT to bail....
1977	// DDCAPS_GDI, DDFXCAPS_BLTMIRRORUPDOWN, DDFXCAPS_BLTMIRRORLEFTRIGHT
